The means here shown comprises a bolt 10 mounted at that end of the band towards which the heads 7 face. The bolt is mounted in a bracket 11 fixed on the outer face of the band and is disposed at an obtuse angle relative to the adjacent end of the band. The bolt projects through a special slot 12 provided therefor in the rim. I then place on the inner end Vof the bolt a `suitably cut vwasher 13 with a nut 14 on the bolt at the ets are in this position the heads 7 will have a-wedgingengagement with the rim beyond the slots. Y

The total length of the two bands is suHiciently less than the circumference of a rim so that one band may be shifted the neces- Y .sary distance about the rim onek way or the otherV without interfering with the other band.

Two bands being used, as hereinbefore stated, one band may first be placed on the upper portion of the wheel, and the latter then rotated to bring the opposite portion uppermost for installation of the other band. This avoids the necessity of jacking the wheels up, as will be evident.

If the wheel is of the double tread type, as in some tractors, four 0r more bands, two or more on each tread, would be used.

In the form of attachment shown in Fig. 3 the band la has a plurality of rubber pads 15 vulcanized or otherwise 'xed thereon instead of the metal grouters. Regardless of the number of pads the same number and spacing of thekL-head members 7a Ais retained as in thek first described type. Thisv enables the lattertype to be installed on the same Wheel for which said first type is designed.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein. p

While this specification sets forth 'in detail Vthe present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not-form a departure Vfrom the spirit of vthe invention, as defined by the appended VI claim as new and useful and' desire to seclaims. i

Having thusrfdescrlbed my invention-what cure by Letters Patent is:

1. A grouter attachment for Vvehicle Ywheels comprising a band to abut against and 'follow thecurvature of the rim of the and follow the curvature of the rim of the wheel, grouters projecting outwardly -from the band, and secured thereto, the rim'having circumferential slots, members fixed on the band to project through the slots, and

means whereby if the band is then rotated in one direction on the rim said band will be held against outward movement relative to \t'he` rim. v

3. A structure as in claim 2, in whichadditional means is provided between 'said bandl and rim for then holding the band against retractive movement on the rim.

4. A grouter attachment for vehicle wheels comprising a band to abutagainst and follow the curvature of the rim ofthe Wheel, grouters projecting outwardly Vfrom the band, means securing the grouters to the band, the rim having circumferential slots, said meansV being arranged to project through the slots, and L heads on' the inner ends of said means of a shorter length than said slots and disposed longitudinally thereof whereby said heads may also be projected through the slots; said heads lying adjacent the inner face of the rim beyond the slots when the band is then turned on the rim.

5. A grouter attachment for vehicle wheels comprising a band to abut against and follow the curvature of the rim of the wheel, grouters projecting outwardly from the band, and secured thereto, the rim having circumferential slots, Vmembers fixed onthe band to project through the slots, L

'heads on the inner ends of said members of a shorter length than said slots and disposed longitudinally thereof whereby said heads may also be projected through the slots; said heads lying adjacent the inner face of the rim beyond the slots when the band is then turned on the (rim, and vadditional means applied to the band andv rim for detachably preventing retractive movement' oi said members along the slots.

6. A grouter attachment for vehicle wheels comprising a band to abut against and follow the curvature of the rim of the wheel, grouters projecting outwardly from the band, and means'on the'band cooperating with the rim whereby if the latter is placed against the rimand then turned in onedirection on the rim, said band will be automatically held Yfrom radial displacenient and further rotativemovement in the same direction. i

7. A structure as inclaim', in which ad- 1,583,890 Y v Y t 3 clitiona-l means is cletachably applied to the Warclly from the bands, and means `applied band and rim for tlienpleventing retractivev to the bands and cooperating with the rim a movement of the band.
